You are a specialist assigned to seek and destroy alien parasites that embed themselves in the bodies of our galactic explorers. The nanobots are microscopic drones loaded onto chips and embedded in each crew member before departing on their missions. You operate these nanobots from a safe sterile station that protects you from the chance of infection. Precision, reaction time and intelligence are your greatest skill requirements in navigating the nanobots. Be aware that some of the alien parasites are faster, tougher and more intelligent. Good luck, the team is counting on you to save them.
